Bought this jacket on the lead up to a 3 day trip in Scotland, weather was to be a bit unpredictable (as normal) but mostly warm. I’m so glad I had this jacket, when the temperature was up I had the liner out and the airflow was mega, really comfortable and lightweight jacket. When you put the liner in it becomes a 3 season jacket, great heat retention, thankfully I didn’t have to test the waterproofing but I’m sure it’ll perform very well. Very happy overall with this and will be a go to jacket for me over the biking season!
